OK, just done a quick scan of the thread, but your problem may be the "intelligent" channel selection algorithms on the sagecom router. It will dynamically change your wifi channel, no matter what your router is set to, "auto" or your specific chosen channel. That is why your channel changes from your selection.

Quite a few people having problems with this router feature which does occasionally seem to pick the "worst" channel rather than the "best". Widely reported on the TT Community Forums.

You need to get in touch with TalkTalk to have this switched off.

Hmmm interesting. TT or TTB who I am with? Might be easier to switch off wifi on the router.

Who do you pay your bills to ?

If you are a TT Residential customer it is easy - just post your request on the TT Customer Forums.

If you are a TT Business customer I guess you would have to ask them - I have no idea what their support structure is like.

Good luck.

TTB. I will ask the question.

TTB have no access to router settings according to an agent this morning. So I guess the answer is just to switch wifi off.

Well, FWIW, my understanding is that it is not a router setting.

It is a line parameter 100% under the control of TalkTalk and can only be changed by TalkTalk technical staff.

Guess paying the extra for "business" level support doesn't buy you any better level of support. Residential customers can have this done on request as a simple change by the forum OCE's (who are TalkTalk staff).

I'll have another go tomorrow, maybe I was asking for the wrong thing.

It's not a line parameter. It is a router setting (hidden).

How on Earth can a WiFi channel be changed by a line parameter?

It's a router setting, not available in the GUI.
Talktalk use TR-069 to disable it within the router.

Absolutely ridiculous to require support staff to disable this imo.
I've commented on this in the Talktalk forums a couple times.

You weren't.
Talktalk residential phone staff are just as clueless to this setting.
It's only really the OCE's on the community forum that know what they're doing.

Here's about 101 examples of Talktalk disabling WiFi channel optimisation on the Sagemcom Fast 5364 after customer requests.

This sort of rubbish is why we need a genuine interoperability standard for new style voice lines over data services. So we can replace ISP issued routers and avoid this rubbish.
